An account earns simple annual interest. You deposit $600 into an account at 5% interest rate for 2 years. (a) Find the interest earned. (b) Find the balance of the account. *

(a) $60 | (b) $660

Step-by-step explanation:

We can use the simple interest formula for this:

I = interest amount

P = principal amount

r = interest rate (decimal form)

t = time (years)

First, change 5% into its decimal form:

5% -> -> 0.05

Next, plug in the values into the equation:

The interest earned is $60. To find the total balance, just add the $600 back.

The total interest earned is $60 and the total is $660.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
